Technical field
The present invention relates to a kind of watering apparatus, relate in particular to a kind of automatic watering device.
Background technology
Existing watering apparatus is of all kinds, material also has various materials, function is also more complete, but the people who grows flower need to often spray water on flowers, often just forget for some owner in addition and water, perhaps sometimes need to go on business the family no one, so the foster flower of family just cannot water, and causes flowers and plants dead.Existing flower pot with automatic watering function, often somewhat expensive, can only water a potted flower simultaneously.
Summary of the invention
In order to overcome the above problem of prior art, this patent has proposed a kind of watering apparatus, not only can be intelligent according to the soil moisture automatic watering, and can realize watering simultaneously several potted flowers, low price.
Automatic watering device, comprise nozzle, water tank, water pump, automatic control module, humidity sensor, digital control panel, wherein, humidity sensor is connected to the humidity sensor of automatic control module and puts into flowerpot soil, water pump is in water tank, water tank has water inlet, nozzle is connected with water tank by connecting rod, described automatic control module comprises the CPU microprocessor, electric supply installation, operational amplifier, power isolation module is electrically connected respectively signal gathering unit, output unit, described signal gathering unit accesses described recognition unit, and wherein liquid crystal display and guidance panel form digital control panel, and connecting rod can arbitrarily rotate.Described nozzle needle is to different situations, and nozzle has respectively a plurality of models.Described electric supply installation can be battery pack, also can plug power device.Described automatic watering device can arrange according to different flowers the different humidity value.Described water tank two ends are provided with handle.Described nozzle can be by manually carrying out switch, and connecting rod is dismountable.
The CPU microprocessor is single-chip microcomputer, the signal sampling unit is the rotating speed that samples, the recognition unit that the system pressure signal is delivered to the CPU microprocessor, after its identification, processed by arithmetic element, carry out logical operation, form a series of data codes that the CPU microprocessor can be identified, by processing unit signal is carried out digital-to-analogue conversion, after amplifying unit amplifies, by output unit control signal is outputed to each executing agency and water.
Described control system adopts fuzzy control.Control system adopts Fuzzy Adaptive PID, to gather calculating with the output quantity according to humidity sensor, then deliver to the system assignment module, giving each branch by suitable regular allocation, is by the isoparametric induction of humidity, induction is transformed into signal is transferred to system, system is according to the humidity parameter of setting, send instruction plant equipment is adjusted, immediately transmit humidity humidity parameter dynamic and default by sensor simultaneously and compare, prevent the situation of excessively watering.
The invention has the beneficial effects as follows, adopt the differences measure of watering according to different flowers, according to the soil moisture automatic watering, avoided simultaneously causing flowers and plants death because forgetting to water or go on business.

Embodiment
Such as Fig. 1, a kind of automatic watering device, comprise nozzle 2, water tank 3, water pump, automatic control module, humidity sensor, digital control panel 1, wherein, the humidity sensor that is connected to automatic control module is put into flowerpot soil, water pump is in water tank 3, water tank 3 has water inlet 5, nozzle 2 is connected connection by connecting rod 4 with water tank, automatic control module comprises the CPU microprocessor, electric supply installation, operational amplifier, power isolation module is electrically connected respectively signal gathering unit, output unit, described signal gathering unit accesses described recognition unit, wherein liquid crystal display and guidance panel form digital control panel 1, and connecting rod 4 can rotate freely the position of putting with corresponding flowerpot, conveniently waters.Nozzle 2 can be by manually carrying out switch, and connecting rod 4 is dismountable, can adopt for the flowerpot of varying number the connecting rod 4 of varying number, and connecting rod can rotate freely the position of putting with corresponding flowerpot, conveniently waters.
Such as Fig. 2, automatic control module comprises CPU microprocessor, electric supply installation, operational amplifier, and power isolation module is electrically connected respectively signal gathering unit, output unit, and described signal gathering unit accesses described recognition unit.Electric supply installation can be battery pack, also can plug power device.
Such as Fig. 3, the CPU microprocessor is single-chip microcomputer, the signal sampling unit is the rotating speed that samples, the recognition unit that system's moisture signal is delivered to the CPU microprocessor, after its identification, processed by arithmetic element, carry out logical operation, form a series of data codes that the CPU microprocessor can be identified, by processing unit signal is carried out digital-to-analogue conversion, after amplifying unit amplifies, by output unit control signal is outputed to digital control panel 1 and water with each executing agency.
Such as Fig. 4, comprise following regardless of the humidity setting section in setting: when device is sold the humidity data expected value; System's humidity sensor adopts hermetically sealed accurate reed-type humidity sensor as the signal sampling of system pressure, has the sampling precision height, and working stability is reliable, and stainless steel material is made, and is corrosion-resistant, anti-vibration, standard thread interface; Comparison signal output: under the automatic operation mode, soil moisture compares with setting humidity, goes control whether to open nozzle according to comparative result output continually varying voltage signal, regulates engine revolution speed control system pressure, until system pressure and setting pressure complete equipilibrium, shut-off nozzle.
